Abstract

An upper elongated slot lifting basketball stand comprises a base, a vertical rod fixed on the base, a fixing board at the upper end of the vertical rod, two groups of lower swing rods, two groups of adjusting rods, two groups of upper swing rods, a backboard and a basket. Two groups of lower fixed supports and two groups of upper fixed supports are arranged in the front of the fixing board, and two groups of lower movable supports and two groups of upper movable supports are arranged in the back of the backboard. A lower fixed point hole of each lower swing rod is hinged with the corresponding lower fixed support through a lower fixed shaft pin, a lower movable point hole of each lower swing rod is hinged with the corresponding lower movable support through a lower movable shaft pin, an upper fixed point hole of each upper swing rod is hinged with the corresponding upper fixed support through an upper fixed shaft pin, a upper movable point hole of each upper swing rod is hinged with the corresponding upper movable support through an upper movable shaft pin, a fixing hole of each adjusting rod is hinged with a middle point of the corresponding lower swing rod through a fixing shaft pin, and an adjusting elongated slot of each adjusting rod is fixed with an upper rod elongated slot on the corresponding upper swing rod by the aid of a bolt-nut set. When the height of the basket needs to be adjusted, the bolt-nut sets only need to be loosened, the basket is moved to the needed height, and then the bolt-nut sets are screwed down.

Description

A kind of upper elongated slot lifting basketball stands

Technical field

The utility model belongs to sports goods, is specifically related to a kind of upper elongated slot lifting basketball stands.

Background technology

Basketball is the sports item that liked by people, popularity rate is higher, arranges but most basketball stands all are requirements according to the regulation game standard, and it highly all is changeless, the calibrated altitude that basketry is liftoff is 3.05 meters, and the men and women is the same height.Very unfair for the not high crowd of individuality like this, especially unfair to the woman, can't make the graceful stimulation actions such as the aerial dunk shot of picture, affect especially the vast minor of middle and primary schools to interest and the enjoyment of basketball movement, be difficult to satisfy extensive crowd's motion requirement.

Summary of the invention

The purpose of this utility model provides a kind of Liftable basketball stands that can convenient adjustment differing heights.To achieve these goals, the utility model adopts following technical solution:

A kind of upper elongated slot lifting basketball stands, comprise that there is fixed head the vertical rod that is fixed with on the base, vertical rod upper end, also comprise two groups of draft links, two groups of adjusting rods, two groups of upper pendulum bars and backboard and basketry, as improvement: described fixed head front has respectively decides under two groups to decide bearing on bearing and two groups; There is respectively under two groups moving bearing on moving bearing and two groups at the described backboard back side; The lower fixed point hole of described draft link and describedly decide to have between the bearing lower dead axle pin hinged down; There is lower moving axis pin hinged between lower moving some hole of described draft link and the described lower moving bearing; The upper fixed point hole of described upper pendulum bar and describedly upward decide to have between the bearing upper dead axle pin hinged; There is upper moving axis pin hinged between upper moving some hole of described upper pendulum bar and the described moving bearing; Have between the fixing hole of described adjusting rod and the intermediate point of described draft link that fixedly pivot pin is hinged; Fix with the bolt and nut group between the adjusting elongated slot of described adjusting rod and the upper boom elongated slot on the described upper pendulum bar.

As further improvement: the horizontal projected area of described base is between 1 square metre to 3 square metres; The sectional area of described vertical rod is between 20 square centimeters to 40 square centimeters; Distance is between 1.2 meters to 1.6 meters between described lower fixed point hole and the described lower moving some hole; Distance is between 1.2 meters to 1.6 meters between described upper fixed point hole and the described moving some hole; Describedly decide bearing and describedly upward decide between the bearing distance between 0.6 meter to 0.8 meter down; Distance is between 0.6 meter to 0.8 meter between described lower moving bearing and the described moving bearing.

The beneficial effects of the utility model are: in the time of adjusting the basketry height, only need unclamp the bolt and nut group, basketry is moved on to desired height, the bolt and nut group be tightened just can again.

When unclamping the bolt and nut group, the movable parallelogram of the four-point articulated formation of lower dead axle pin, lower moving axis pin, upper dead axle pin and upper moving axis pin can be controlled backboard and make up and down vertical oscillation, moves up and down with basketry.

Have between the intermediate point in conjunction with fixing hole and draft link that fixedly pivot pin is hinged, when regulating between elongated slot and the upper boom elongated slot with the bolt and nut group fixedly, the static parallelogram of the four-point articulated formation of lower dead axle pin, lower moving axis pin, upper dead axle pin and upper moving axis pin is by two trapezoidal replacements: namely descend dead axle pin and upper dead axle pin and fixedly the first trapezoidal and time moving axis pin of being consisted of of pivot pin and bolt and nut group and upper moving axis pin and fixedly pivot pin and bolt and nut group consisted of second trapezoidal, displacement no longer.

Be implemented in the height of controlling backboard and basketry in sizable scope by easy operation, guarantee simultaneously backboard all the time perpendicular to ground, thereby realize allowing more crowd experience basketball enjoyment.The utility model is novel, manufacturing is simple, simple operation, possesses popularizing value.

The utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
